-accusa: cHnoNIK- AND LoUIs cnlioNI'K, or NEW YORK, inv.'

Be it known that ive, AUGUST CHRONIK and LOUIS' CHRoNrK, citlzens of the United States, and residents of the city of New Yorlgin the county of New -York and State of NewYork, have invented certainnew and useful Improvements in Film-.Perforating Machines, of which the following is a lspeciication.V

The present invention relates to machines for perforatin films of moving picture exhibitors, or'ot er material.

One of the'objects of the `invention is to provide a deviceof .this`-cl1aracter which :'YPrQYide a locking advances positively in a uniform'manner the films or other materialjso that any dead motion'of feeding mechanism is avoided.V

Another object ofthe invention is to provide' a silnple and efficient operatingmeans forvarying the advaneingmovement of the feeding mechanism, atw1ll. r

A further object of the invention `is to provide a vcombinedpunching andjfeeding mechanism, whereby 'fthegcoperating' perfo: rating membeifsare adapted `to advance `the material after each perforation, to return to their normal ositions again on being dis-4 -V engaged from t e material. l l I A still` further object of th invention is'to mechanism for holding the film firmly in its vposition during its period of,V rest.

' Withftlisefand {.other, obiects in view,

will more fully appear as the nature of the invention 'is better understood, the same consists in the novel combination, arrangement and construction of parts, which will be hereinafter more fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that various changes. in the size, construction, arrangement of the parts and minor de tails of construction may he made without departing from the airit or sacrificing any vantages o of the a the invention.

One' of the many possible embodiments of the invention4 isillustratcd in the accompanying drawings, in which Figure l is a' front elevation, partly in section, of a film perforating machine .constructed in :meordancez with the present invention; Fig. 2 is a section taken on line 2+2 of Fi 1; F ig. 3 is asection taken on line 3-3 o Fig. 2; Fig. 4 is a section taken Specification of Letters Yatent.

Y In the drawings, the numeral 7 indicates i similar y-arrangedonthe sides o f the base,

is mounted a countershaft 13,`carryin ulleys 14 andv15. The pulley.14. 1s riven through theintermediary of a flexible con'- `nection, s ch .s a rope 16, b va ulley 18,

' 'the end's ofp arranged upon one o themain shaft 10, which latter may be rotated by hand.' by means of a ,crank 19, or may be Iactuated by. any suitable source of power,

such as for instance an electric motor. The pulley 15 is connected by means Aof another flexible .connection 20 with a pul1ey'21,-`coupled by means of afriction-fclutch'with a spindle 22, which -is journaledina bearing 23, carried bya bracket 24, the vlatter being attached in any suitable 'manner vto the ba'se Z of the motor.. Upon fthe spindle 22 is mounted I the 'receivin reel {not shown), whileythe delivery ree is monted upon a spindle.25, j ournaled in a bearing 25,whi'ch is attached by means of a' bracket 26 to the base of the device.` A fly-wheel 27 is mounted upon the other end of the main shaft 10 for obvious reasons.

vertical pests or standards 28, astre at! i tached tothe base and connected at their upper ends by means of a brid e 29',l which is provided at its center with a ole 30, into which lits the reduced portion 31 of. a screw threaded spindle 32. The.up er end of the spindle 31 protrudes throng the hole 30 and carries fixcdly attached thereto an oprating crank 33. As will -be observed from .theinspection of the drawings, the screw threaded spindle, while adapted to rotate in its bearing in the bridge 29, cannot be shifted in the direction of its longitudinal axis, whereby a nutmesliing with t e Screw threaded spindle is ada. ted to be shifted in the direction of said ongitudinal axis, if

held against rotation. The part, which it is intended to shift in the direction of the prises a frame 34, provided upon its four corners with sleeves 35, 35 in sliding engagement with the posts 28. This frame is 2 e v 979,429 l provided in its cross-piece 3(3.with a screw threaded hole 3i', the threads of which mesh with that of the spindle 32.

.The female die et. the device is designated by the numeral 3S, and comprises a plate -member 39 having holes 40 and 41 therein, which are arranged at a distance lwlneh corresponds to that of two rows of perforatlons intended to be punched into the two sides of the tihn. Upon the die plate 39 are arl ranged the strippers 42 and 43, which are provided with holes .l-t and tft registering-l with the holesl 40 and 4l. The female die fork 54, between the prongs 'of which is'ar- 'ranged an eccentric 55, mounted upon the The male-die of .the de'iicc comprises a head 5G, slidalily mountedf'iipdn ftherds'46i and 4T. and carrying the punches 5'1", 57, in

' aliueuieut with the holes t0 and -1-1 of the tianale` die. The means for actuating the uiate die. comprises two eccentries 5S, arranged upon the main shaft 10` aud set at', ISO" relative to the ercentric These eceentrifs 51S. 5S engage the prongs of theforks 5H. 59. oscillat'ably mounted upon a spindle 60, which isattaehed to the base'iP of the device. :The forks'i11e1connectial by nie'ans of` hars Gl. t3! with'the dieta-ad 5G, and more particularly in such a manner that both ends of said bars are pivotcd to the forks and the die head, respectively. 4j rl`he means forholding th'e tilni in position during theoneration ofthe punches com-A prise presser feet C2. tl. mounted upon spindies 63. G2, which are slidablvarranged upon 'the base, Aand provided at their lower ends with disks or heads ('14. Springs ('15, (i5, bearing against' the .haw :1 11dthe heads (i4. keep the presser feet in contact with the tihn, to hohl the same tirnilv i-n its position. 'lo release the film. the forks 59 are provided with fingers G0', upon which are mounted"sct screws ft', which cooperate with the heads (it, in the manner hereinafter described, in order to lift the presser feet.

From the inspectioli o't' the drawings it will be. observed that the. eccentric 55. in cooperation with the. fork 54, oscillates the telnale die 3S togetherl with -all of those parts which are mounted upon tht-,rods 4G and 47. 'lhese rods engage the holes (36. 6G in ablock 67, which is oseillatably mounted upon the cross-piece ft b v means et' pointed sat screws (18. G8, 'this block is provdided with a hole. G9. which is engaged bi.' the supporting bar 5t, theI width of said hole bein'f larger than .the cross section of the bar, whereby the latter is adapted to oscillate relative to the block. The purpose of this arrangement will be hereinafter more fully explalried. i 5

The operation of the device is as follows: The end of the tihn is placed between the presser feet (r2, stripl'iers 4.4 and 45, andattachcd to the receivuig reel, which is'rnouxited upon .the spindle 22. As the crank 19 is nowvretated, thefollowing operations will take place, considering the position shown in the drawings as the position of rest: 'lhe eccentrics 58, 5S will torce the forks 5S), 59 downward, whereby the tihn is perforated by the. punches'fi, 57. As the punches are l being forced downward, the lingers (20' of the forks 59 are moved upward, whereby the presser feet 62 releasethe tilm at or after .i

the end of the punching operation. Upon. further rotationof the main shaft- 10, the eccentries 58,158 hold the punches 57 in engagement with the female die and thus with the tilm, and theeccentrig' -forees the lower end of the'ork 54 toward the spindle bloek (i7 relative tothe female die 39; ir in otherrwords by the distance at which the -ielrmlcftlie. 3S is pivoted to the frame of -the device. This distance. can be obviously .varied by turning tl'ielpranlt El?, in one or the other direction and raising or lowering thus the block G7 relative to the base i'. 'l`he higher the block is raised. the greater is the distance between theperforatio11s and conversely the lower itis brought. the less is the. distance between the same, or in other words if the block is raised, the number ot perforations upon one foot. of the ilin' if; decreaseth. while. when lowered. the number is increased. Obviously one of the posts 28 may be. graduated, whereby the desired position of the block relative nto the base plate can be easily found.

VVhil'cherein the device has been described For films for moving picture exhibitors` it will"be ol-iserved that the machineean be. madouse of for pertiorating-other articles also.
